WOOD-DISTILLING APPARATUS.

i SPECIFICATION forming part of Letters Patent No. 275,461, dated April10, 1883. I

A Application tiled September 27, 18H2. (No model.)

To all whom it may concern Beit known that I, CHARLES J. T. BURCEY, ofSyracuse, in the county of Onondaga, in the State of New York, haveinvented new and useful Improvements in Wood-Distilling Apparatus, ofwhich the following, taken in connection with the accompanying drawing,is a full, clear, and exact description.

This invention consists in the novel means of deodorizing wood-alcohol,as hereinafter fully described, and specifically set forth in theclaims.

, The annexed drawing represents an elevation of my invention, shownpartly in section to better illustrate the internal arrangement of someof its constituent parts.

A represents the top portion of a wood-alcohol distilling apparatus, theheavier products of distillation being separated from the vaporousalcohol by deiectiug-plates e e, arranged inside of said distillingapparatus, and the lighter or more volatile portion ofthe alcoholpassing upward through the top opening, f, from whence they havehitherto been conveyed to suitable condensers. Instead of im mediatelycondensing the said alcohol, I pass it in-v to a reheati-ng apparatus,B, in the form of a steam drum or cylinder, mounted on topl of thedistillng apparatus'A, and having at a proper distance from its ends twodiaphragms or line sheets, h h, to which is connected aseries of iiues,aa, extended longitudinally through said drum and open at theirextremities, thelower end ofsaid flues beingthus made tocommunicate-With the subjacent distillin g apparatus A.

To the upper end of the steam-drum B is connected a pipe, C, which isextended into a tank, D, through the top thereof and terminated near thebottom of the same. This tank is made air-tight and provided on top witha suitable inlet, N, through which to introduce soluble glass, or asolution of silicate of potash or silicate ot' soda, formed of 22 partsof silica, 13.5 parts of soda, and 64.5 parts ot' water, giving asoluble glass of a density of 1.25 to 1.28. An outlet, o, provided withastop-cock,

emptying the same when desired.

To the discharge end of the pipe C, I conneet two concave-convex disks,b c, withtheir concave sides facing eachother and joined at their edges.The bottom disk, c, is perforated,

and, in conjunction with the upper disk, Z, serves to thorougly diusethe vapor alcohol passing from the pipe C through the perforations ofthe disk c. The bottom of the lower portion ofthe vertical sides of thetank D is surrounded by a steam-jacket, I, which receives steam from apipe, K, connected with asuitable steamgenerator. A branch pipe, L,extended 6o from the steam-pipe K and tapping the drum B, between thetwo flue-sheets h h, conveys steam to said drum for reheating thealcohol passing through the ilues a a of said drum. From the top of thetank D is extended a pipe, 6 5 E, which communicates with theinductionport of the exhaust-fan F. From the dischargeopening of the fanF is vextended a pipe, E', which is connected with a coil-pipe, El,situated in a water-tank or condensing-vat, 7o G, the extremity of saidcoil passing out through the side of the vat G and delivering thealcohol in acondensed and deodorized state.

l denotes a float placed inside of the receptacle Dand having a cord orlight chain, d, extended through the top of said receptacle and overpulleys, and provided on its end with a sufficient weight, m, tomaintain the cord or chain taut, said iloat having the requisitebuoyancy and weight to rise and fall with the 8o soluble glass in thetank D, and, by the corresponding rise and fall of the Weight m,indicating the depth of the soluble glass in the tank.

The operation of the described apparatus is as follows: The tank D is tobe partly lled 8 5 with soluble glass, then the distilling apparatus Abeing set in operation the light and vaporous products of distillationascend therefrom and pass through the ues a a of the steam-drum B, andthence through the pipe C 9o to the tank D. The discharge end ofthe pipeC, being submerged in the soluble glass, cornpels the vapor as it issuesfrom the pipe C to pass through said soluble glass to the space aboveit. The deiiector b, in conjunction with 9 5 the strainer c, serves todiffuse the vaporin its passage through the bath of soluble glass. Theflow ofthe vapor is acceleratedby reheating the vapor to about 66Ocentigrade in the steam-drum B, and to about 700 centigrade roo in thetank D. This is accomplished by turning on the steam through the pipes Kand L. From the tank D the vapor is drawn through the pipe Eby the fanF,which forces it through the condensingcoii H. The suction of the fanproduces a vacuum in the upper part of the tank, and thus facilitatesthe cireuiation of the vapor through the bath of soluble glass. p Thisbath eiectnally deodorizes the wood-alcohol.

Having described my invention, what I claim s l. The combination, withthe distilling apparatus A, ofthe steam-drum B, having dues a a,communicating with said apparatus, the tank D, pipe c, terminating nearthe bottom of said tank, pipe E, fan F, and condenser G, substantiallyas and for the purpose set forth.
